TO ALL WHOM IT MAY CONCERN:

Be it known that I, W. O. HICKOK, of Harrisburg, in the county ofDauphin, and State of Pennsylvania, have invented a new and usefulImprovement in Paper-Ruling Machinesyand I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference -being had to the accompanying'drawings, making a part of this specication, in which-- l Figure 1 is aperspective view of one of the said improved machines broken away acrossits middle in order to narrow the figure. Y

Figure 2, a. vertical transverse section of part of the same cut throughthe centres of the turning points of the pen-beam; and

Figure 3 a vertical longitudinal section of theisliding standard, whichsupports the further end of the pen-beam.

Like letters of reference indicate the same parts when in the different`iigures. f

Although the pen-beam of paper-ruling machines has been supported uponstandards and bearings made adjustable-by means of slots and screw-nuts,or by means of thumb-and-inger screws, in combination with slidesand'jam-nuts, for the purpose of enabling the attendant to adjust thepen-beam with accuracy and facility, to suit defects in the form of thepaper, many of the reams in a lot of paper being often trimmed or cut atirregular angles, yet the diierent devices heretofore produced for thepurpose are still more or less defective, especially in that they do notprovide against the very objectionable binding or strained result uponthe beam and its bearings, arising from the movement ofthe nearer one ofthe supports ofthe pen-beam, while the otherl or further one isstationary, relative conditions which are almost constant.

The object of my improvement is to avoid this objection; and myinvention consists in the 'construction and application of' avperforated ball in combination with a sliding stem, so as to afford aball and sliding joint, for the further end of thepen-beam,substantially as hereinafter described.

My invention also consists, in combination with the'said ball andsliding joint, the employment of a solidball joint, for supporting thenearer end ot' the said pen-beam, substantially as hereinafterdescribed; and my invention also consists, in combination with the saidtwo ball-joints, the application of the standards, so that they can beslid longitudinally along on the table or frame of the machine withgreater accuracy and facility as the required adjustments of thepen-beam may from time te time require during theoperation of themachine,

substantially as hereinafter described. v i v Referring to the drawings,A is the pen-beam; B B', the sliding standards; C C', fixed supports forthe sliding standards; D D', the ball-joints; E E', stems, which connectthe respective ball-joints and standards to the twoy'ends of thepen-beam; and F, sections representing the table or frame of themachine. n

The standard B consists of a post, b", having a dat foot, 6"', wherebyit is supported-in a verticall position, and so that i-t can be slidalong'backward and forward on its base, C, which is fixed permanently`to the frame, F, of the ruling-machine. V

Projecting on the front side of the post b" there are two fixed lugs, b*through both of which a thumband-finger screw, g, is secured, so that itcan be rotated without screwing inthe said lugs. Between the lugs b4 b5,a block, g', is iitted to slide accurately up and down the post b", whentbe screw g, which screws through it, is rotated accordingly.Transversely through this sliding block g', another thumb-and-fingerscrew,vg", works, and which is ittedwith ajam-.nut,';q"', at the outerside oi' the post b", whileits inner end is finished` with a bau, g3(see ng. 2.)

The rear end of the base, C, of the post b" hns an upright,'c", in whicha thumb-and-nger screw, c'", is secured in a horizontal position by ahead und jam-nut thereon, so that it can be rotated without screwing inthe upright, c", and on the slide b"' there is a corresponding upright,i6, through which the said screw 0"' is caused to move the slide inadjusting the standard B', (see fig. 1.) V'

On that end of the pen-beam A, which connects with the bali y', there isfixed a two-part clamp, a' a",

the part a." being detachably secured to the parta'. Between these twoparts a spherical Vcavity is made for the reception of the ball g4 onthe end of the screw y", so that the said cavity, with the said ball onthe end of the screw g", will form together the ball-joint D, asuflicient space being made around between the screw-stem and the outeropening of the cavity to allow the required motion in the joint, as'willbe hereinafter referred to. The standard B'. is supported in a verticalposition, and so that it can be slid backward and forward in a fixedbase, C', by means of a screw, 0"', precisely in the same form andmanner as upright, B. Projecting from the upper end of the post b"thereof there is a boss, b', through which a screw, H, is caused toslideaccurately up and down by means of a. thumb-and-finger mit, h', abovetheboss 127, ajat'n-nut, h", being applied below the boss for thepurpose of fixing the said screw when necessary. l

The lower end of the screw H has iixed to it a two-part'clamp,.h"', thetwo parts of t" being detachably secured together by screws. Between thetwo parte of the clamp t" there is a spherical cavity, in which aperforated ball, t, is accurately fitted to rotate, and, fixed to thefurther end of the pen-beam A, there is a projecting stein, 11"', whichaccurately fits through the perforation in the ball h4, yet so that thesaid stem can be slidalong within the ball, suicient space being madearound between the open edges of the spherical cavity and the stem toallow the required motion of the ball-joint, as will hereinafter bereferred to.

The projecting stem a"' is fixed in a boss on a plate, a4, which plateis fixed on the cnd. of the beam A, substantially as represented in fig.2. d i l l It will be readily seen that, by means of the ball-joints DD' andsliding standards'B B', constructed and arranged in combinationwith the pen-beam and the frame or table of the machine, as described,the said penbeam, with its pens attached, can be instantly adjusted withfacility and perfect accuracy, to suit any inequality in the paperpassing under them, and without any binding or straining, because arotary motion given to the screw g" will give an exact longitudinalmotion to the pen-beam. t A like rotary motion given to either of thc'screws g and L will give an exact vertical motion to either end of thepen-beam.' A like rotary motion given Ato either ofthe screws, c", ofthe slides, will give an exact horizontal motion to the said beam, 'andtherefore,

the beam being suspended by the ball-joints D D', any movement requiredin the said penbeam canbe instantly and accurately given with` facility,and without causing any bindingor strainingv Whatever at any part of thebeam. t

--It will also be seen that the manner in which the axis or stem, a', ofthe further end of the pen-beam is applied thereto,` is an improvementof importance, as it affords, not only a more substantial axis, butadmits of greater accuracy in itsapplication to the beam. p

Having thus fully described my improvement, -what I claim as newthereinV of my invention, aud desire to secure by Letters Patent, isconfined to the following, viz:

1. I claim suspending the peu-beam of a paper-ruling `machine by 'meansof the ball-joints D-and D', in combination with sliding standards, Band B', operating together, substantially as and for the purposedescribed.

2. I claim the ball-jointD',4consisting of the socket It* and theperforated ball therein,`in combination with the stem a'" on the end ofthe pen-beam, thesaid parts operating together substantially in themanner described.

3. I claim,in combination with the peu-'beam A and sliding ball-jointD', the solid ball-joint D, consisting 4of the sphericalcavity withinthe clamp a' off'lon the end of the pen-beam A, and the solid ball g4 onthe end of the screw g", the said 'parts being constructed' and arrangedto operate substantially as and for the purpose described. i, i

4.' I claim, in combination with a pen-beam, A, suspended upon thebal1j0ints D and D', as described, the sliding standards B and B',operated by means of their respective screws .c" 6"', substantially asand 'for the purpose described. `l l p v v 5. I claim, in combinationwith the pen-beam of a ruling-machine, the stem a', constructed andapplied substantially as andfor the purpose described. Y.
